An unseasonal dust storm has swept through the Middle East, blanketing Beirut and Damascus, killing at least two and hospitalizing hundreds in Lebanon, and halting airstrikes in neighboring Syria where five people have reportedly died due to the freak weather.

People across the region have posted stunning pictures online of huge clouds of dust that speak for themselves. The deadly sandstorm is so large it can be seen from space. NASA has shared an image of the raging dust and sand, which caused breathing problems, reduced visibility in parts of Lebanon, Syria, Cyprus, Israel and Iraq and even forced school closures.

"It is unbelievable. This must be some test," Mansour, a Damascus resident, told AP. "It's hot. Temperatures are high and above that we have this dusty weather! It is something beyond reasonable. Enough please!"

The Lebanese Health Ministry said that 750 people had been hospitalized with respiratory problems, and asked local residents to go outside only with face masks.

Syria's state-run news agency SANA reported that three people in the central Hama province had died in the sandstorm, adding that there were "over 3580 cases of asphyxia, dyspnea, breathlessness and asthma were reported by directors of health departments in several provinces."

Rami Abdel Rahman, head of the Syrian Observatory for Human Rights, told AFP: "There were four [killed] in Deir Ezzor, including a child and an elderly woman, as well as another child in Hama province and a person in Daraa." According to the group, there were fewer airstrikes in Syria on Monday due to the storm.

In Jordan, schools either shut down or sent children home early, AP reported. In Cyprus, aircraft had to be diverted to Pathos from Larnaca’s airport after visibility fell to 500 meters.
